M2TS (MPEG-2 Transport Stream) is a Blu-ray BDAV container format that uses MPEG-2 transport stream and comes with a .m2ts filename extension. It can manipulate audio, video, and other metadata such as disc menu and subtitles. At a bare minimum, any Blu-ray player should play M2TS files easily.
MPEG-2 is a digital video coding format introduced in 1995 and later revised in 2013. It uses lossy video and audio data compressions and is very popular among video hardware, thanks to its low computational complexity. It is also widely used in cable and satellite broadcasting as well as writing DVDs.
